Changing the staff size in layouts
You can change the staff size project-wide for each layout in your project. For example, you can have a small staff size in full score layouts but a larger staff size in part layouts.
Note
If the size of system object font styles is set to Staff-relative, the staff size of the top staff in each instrument family group affects the size of system objects if they are shown above that bracketed group. Font styles that are set to Absolute are unaffected by staff size.
Procedure
Result
The staff size in the selected layouts is changed project-wide.
Tip
You can also change the staff size from specific points in layouts, and change the size of individual staves.
